GS450h_300h_OM_OM30D53E_(EE)The installation of an RF-transmitter system in your vehicle could affect
electronic systems such as:
Multiport fuel injection system/sequential multiport fuel injection system
Dynamic radar cruise control with full-speed range system
Dynamic radar cruise control system
Cruise control system
Anti-lock brake system
Vehicle dynamics integrated management
SRS airbag system
Seat belt pretensioner system
Be sure to check with any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional for precautionary measures or spe-
cial instructions regarding installation of an RF-transmitter system.
Further information regarding frequency bands, power levels, antenna posi-
tions and installation provisions for the installation of RF-transmitters, is
available on request at any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
High voltage parts and cables on the hybrid vehicles emit approximately the
same amount of electromagnetic waves as the conventional gasoline pow-
ered vehicles or home electronic appliances despite of their electromagnetic
shielding.
Unwanted noise may occur in the reception of the radio frequency transmit-
ter (RF-transmitter).
The SRS airbag and seat belt pretensioner devices in your Lexus contain
explosive chemicals. If the vehicle is scrapped with the airbags and seat belt
pretensioners left as they are, this may cause an accident such as fire. Be sure
to have the systems of the SRS airbag and seat belt pretensioner removed and
disposed of by a qualified service shop or by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional before you
scrap your vehicle.

CAUTION
General precautions while driving
Driving under the influence: Never drive your vehicle when under the
influence of alcohol or drugs that have impaired your ability to operate
your vehicle. Alcohol and certain drugs delay reaction time, impair judg-
ment and reduce coordination, which could lead to an accident that could
result in death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that
other drivers or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that
distracts the driver, such as adjusting controls, talking on a cellular phone
or reading can result in a collision with resulting death or serious injury to
you, your occupants or others.
General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows, the moon roof, or other features of the vehicle. In addition,
heat build-up or extremely cold temperatures inside the vehicle can be fatal
to children.
Your vehicle contains batteries and/or accumulators. Do not discard them
into the environment but cooperate with separate collection
(Directive 2006/66/EC).
